Abstract: A liquid crystal control circuit is provided for driving a MIP liquid crystal panel. The MIP liquid crystal panel has a plurality of pixels, each of which includes a memory element and a display element. The memory element holds electric potential depending on an image signal. The display element is applied voltage depending on the electric potential which the memory element holds. The liquid crystal control circuit includes an inversion unit that inverts polarity of AC voltage in a first mode in which an enable signal is output. The AC voltage being is applied to the display element in synchronization with outputting of the enable signal. The enable signal activates the image signal output to the MIP liquid crystal panel.
